13.3 Analytical procedures – ISSAI 4100
• What are analytical procedures?
ISSAI 4100 paragraph 109/4200 paragraph 116: Analytical procedures involve comparing data, or investigating
fluctuations or relationships that appear inconsistent. In compliance auditing, such procedures may, for example, involve comparing an increase in pension benefits payments from one year to the next with demographic information such as the number of citizens having reached retirement age within the last year. If the criteria relate to the terms of an agreement which state, for example, that project funding is provided based on performance levels such as the number of job placements made, then any changes in project funding might be
compared to changes in employment statistics.

13.4 Applying analytical procedures
• When to apply analytical procedures?
7
Purpose
Preliminary Substantive Final
ISAs
(520 & 315) Required Required Optional
ISA requirements
Assurance Identify risks Draw Conclusion
13.5 Types of analytical procedures
• Ratio’s
• Trend analysis
• Reasonableness testing
• Regressing analysis
• Scanning analysis
8
13.6 Benefits of analytical procedures
• To determine if an extension of the audit procedures is necessary
• Preliminary analytics are mandatory
• Helps identifying unusual fluctuations
• Exceptions are based on expected business evolutions
• No audit evidence obtained !
9
13.7 Analytical procedures – True or False?
A municipalities budget shows a decrease in local tax income for four consecutive years. The auditor compares the trend with:
a) Number of inhabitants
b) Tax level
Is this a correct analysis?
10
13.8 Analytical procedures – True or False?
• A ministry has announced an end to a subsidy scheme as of 31 March on 1 April, allowing all requests arriving on or before 1 April to be considered. The amount spent was within budget.
• The auditor makes an overtime analysis of the amount accounted and notices a significant decrease in April from August and no payment afterwards
Is this a correct analysis?
11
13.9 Analytical procedures –True or false?
After the compliance of a ministry has been examined the HSC reviewer asks you what the explanation is for the increase in the spending in budget item X. You answer that budget item X was reviewed looking at the top 10 items included and no irregularities were found.
Should the reviewer accept this explanation?

13.10 Tests of detail -substantive testing
• What are the types?

• To what extent to examine?
• Ways of testing
• How to do this in practice
13
13.11 Types of testing

• Inquiry
• Observation
• Recalculation
• Recomputation
• Reconciliation
• Confirmation
• Vouching
• Cut-off testing
• Examination
• Use of work of specialists
• Tracing
14
13.12 How many? A possible decision tree
15
No
No
Either expand targeted testing or perform substantive analytical procedures, non-statistical sampling or accept-reject testing on untested items. Reconsider the option to achieve a higher level of controls testing as well.
Can we efficiently test items?
Perform TARGETED TESTING
No further testing required
(document rationale/conclusion)
Yes
Possible & appropriate to project misstatements?
Yes No
Perform ACCEPT-REJECT
TESTING
Perform NON-STATISTICAL
SAMPLING
Yes
Considering the results of tests of controls, substantive analytics and targeted testing, do we need more assurance with regard to the untested items?
Are the aggregated untested items above materiality?
Can we select items within an account or population based on a higher value, higher risk, or other characteristic to
address our test objective?
No
No Yes
Yes
13.13 Tests of detail – ways of selecting
• Risk based
• Judgemental
• Statistical
In all cases:
• Selecting the type of procedure
• Selecting the items to test
